Structural and rDNA studies were conducted on several Asian and African fungi with affinity to the genus Epichloe (Balansieae; Clavicipitaceae; Hypocreales). These species were found to be epibiotic in habit, to produce brown to black ascomata, and to be symbionts of warm-season grasses. Epichloe spp. from Europe and North America are endophytic in habit, produce yellow to orange ascomata, and are symbionts of cool-season grasses. Phylogenetic studies employing the ITS1 region of the rDNA suggest that Epichloe, as defined to include both endophytic and epibiotic species, is polyphyletic. To improve the taxonomy in this group of symbionts, a new genus Parepichloe is proposed to accommodate epibiotic species.
